, cannon-iron common Application filed November I To all whom it mayconcern:

Be it known that I ,.J 'osnrn C. Youne- BLoon, a citizen of the UnitedStates, residing at Atwood, in the county of Rawlins and State ofKansas, have invented certain new and useful Improvements in CarburetorControls; and I do declare the following to be a full, clear, and exactdescription of the as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to the figures of reference marked thereon,which form a part of this specification.

This invention relates to a carburetor con trol and it is particularlyadapted for use in connection with Ford motor vehicles.

The primary object is to provide a simple carburetor control, operablefrom th instrument board of the vehicle, the mechanism consisting of aminimum number of parts and yet of such construction that it will beinexpensive to manufacture while at the same time being efficient inoperation.

The novel construction of the invention will be apparent by reference tothe following description in connection with the ac companying drawings,in which- Fig. l is a detail view of the operating mechanism for thecarburetor, the instrument'board and dash being shown in section.

Fig. l is a detail view of a connecting loep.

Referring now to als of reference:

1 designates the dash, 2 the cowl and 3 the instrument board of a motorvehicle of known construction. The elements just described representcorresponding elements on the present model of motor vehicle made by theFord Motor Company of Detroit, Michi gan and the invention is shown inconnection therewith because it is particularly adapted for use inconnection with such a vehicle. Such a vehicle employs a carburetor likethat. indicated at 4 and it has a needle valve 5 and a choke valve 6. Onthe stem of the needle valve is a plate 7 having openings 8 and 9 toreceive the tines 10 and constitutes a link the drawings by numer- 19,the face 20 of which is a, 1022. Serial in. 598,021."

connection between the manually operated rodv 13 and the plate 7 Theupper end of the fork 12 is bifurcated with ends 15 and I5 bent over toform a split loop 14. The ends 15 and 15 of the loop engage a stud 16.The lower end of the rod 13' is provided with a split loop 17 projectingthrough an opening 18 in the stud 16 'so that the loop 17 extendsthrough the stud 16 and also through the loop 14. Therefore, there is auniversal connection provided between the rod 13 and the forked link 12,the connection being such that a sharp, angular adjustment may be madeby a slight turning of the rod 13. I 1

On the upper end of the rod 13 is a disk referably luminous and the faceprefera words More and Less. The purpose of making the disk luminous isto enable the occupant to find it at night and the object of usingthewords More and Less is to indicate the direction in which the disk isto be turned for a maximum or a minimum gasoline feed or for adjustmentsbetween the two extremes.

Mounted upon the shaft or rod 13' is a stop collar 21 engageable with astud 22 on the arm 23 of a pivoted elbow lever 24 carried by a bracket25 on the dash of the vehi ole, the stop collar being preferablyadjustable on the rod to determine extent of opening of the choke valveand the stud being rotatably mounted on the lever arm to prevent bindingof the rod in the stud when the rod is moved longitudinally, aspresently described.

The other arm 26 connects to a link 27 which, in turn, connects to theelbow lever 28 of the choke valve 6. The stud and stop 22 being looseupon the rod 13 allows the rodd13" to be rotated without afi'ecting thestu The rotation of the rod 13' will impart a rotary motion to the forklink 12 so that the needle valve 5 can be adjusted. By pulling up on therod 13, the stop collar 21 will contact with the stud and guide 22 sothat a longitudinal movement can be imparted to it, causing it to swingthe arm 26 upward and thereby choke the carburetor.

Attention is called to the fact that with this device a single manuallyoperated rod suffices both for operating the choking meohs anism and foroperating the needle valve. The elbow lever for the choke valve is set MUNITED. STATES'rarnnrorrics.

so that it swings over dead center osition, which permits the choking tobe ully accomplished without raising the choked end of the rod out ofthe carburetor adjusting head or plate. Thus I can eliminate thenecessity of extra rods, brackets, sleeves and sliding joints.

The combination stud and guide on the rod 13 which is connected to thearm of the elbow lever makes a simple means for mechanically connectingthe rod 13' to the elbow lever. The combination stud and sleeve servestwo purposes: it acts as a bearing for the rod when adjustment is beingmade and a sleeve for the choking.

The connection between the rod 13 and the elbow lever 25 is very simpleand while it is as effective as similar devices now on the market, it isvery much easier to manufacture and the universal joint renders thedevice extremely sensitive in that it can be operated by a minimumturning movement of the rod 13.

The device is extremely simple to install and will readily perform thefunction for which it is intended.

What I claim and desire ters Patent is:

1. The combination with a motor vehicle of the Ford type comprising adash having an opening therein, a carburetor having separate choke andneedle valves, a bell crank lever mounted on the dash and a linkoperatively connecting One arm of the bell crank with the choke valve,of a carburetor to secure by Letcollar on the second rod engageable withthe stud to rock the bell crank when the second rod is movedlongitudinally.

2. The combination with a motor vehicle of the Ford type comprising adash having an opening therein, a carburetor having separate choke andneedle valves; the latter being equipped with a coupling member, a bellcranklever mounted on the dash and a connecting link between one arm ofthe bell crank and the choke valve, of a carburetor control devicecomprising a rod having idle longitudinal and active rotary connectionwith the coupling member of the needle valve, a second rod extendedthrough the dash opening and having a universal joint connection withthe first rod, a stud having a pivotally fixed supporting connectionwith the other arm of the bell crank lever and having an aperturethrough which the second rod is slidably and rotatably supported and astop collar adjustably mounted on the second rod engageable with thestud to rock the bell crank lever when the second rod is movedlongitudinally.

In testimony whereof I affix my signature.

JOSEPH C. YOUNGBLOOD.
